Check Digit Verification of cas no
The CAS Registry Mumber 175202-58-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,5,2,0 and 2 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 175202-58:
(8*1)+(7*7)+(6*5)+(5*2)+(4*0)+(3*2)+(2*5)+(1*8)=121
121 % 10 = 1
So 175202-58-1 is a valid CAS Registry Number.

Paragraph 0023; 0024; 0025; 0026; 0027; 0028-0036, (2017/08/31)
The invention discloses a method for one-step synthesis of 3, 4-dimethylthieno[2, 3-b]thiophene. The method comprises 1) mixing thieno[2, 3-b]thiophene, substituted methane, an organic base and a catalyst, and carrying out a reaction process under conditions of pressure and protective gas, wherein the catalyst is rhodium carbon having rhodium content of 5wt%, and 2) separating and purifying the reaction system to obtain a product 3, 4-dimethylthieno[2, 3-b]thiophene. Under the pressure auxiliary condition, in the presence of the catalyst, under action of the organic base, groups at 3th and 4th sites of the thieno[2, 3-b]thiophene undergo a nucleophilic reaction to produce 3, 4-dimethylthieno[2, 3-b]thiophene. The reaction yield is 96% or more.

A novel fluoroionophore 1 based on 3,4-dimethylthieno[2,3-b]thiophene bearing two monoaza-15-crown-5 ethers at 3- and 4-positions was prepared. UV-vis and fluorescence responses of compound 1 upon the addition of alkali and alkaline earth metal cations were evaluated in acetonitrile solution. Receptor 1 showed unique response for Ba2+ due to the formation of an intramolecular sandwich complex.
